Kenji Nojima - Eien Dake ga Futari wo Kakeru (Japanese to English)

So I got another song that needs to be translated to English. It happens to be an ending to a popular series but I cannot find translations for it anywhere. There's only the romanization and the kanji. Link to the romanji/song will be here: https://youtu.be/KaeIeyABftc (Unfortunately, I do not want a translation of the Spanish translation.)
